View 1 RepliesI am trying to use dataview.Rowfilter to filter datagridview for users. The basic idea is that user enters a text in a textbox, and then the below function is called to filter the text in all columns, like Col1=value OR col2=value OR col3=value. But I got error message of the filter expression.

This post is a continuation of my other post concerning 'List(of) with multiple comboboxes refill problem.'. I threw the list overboard and began anew with a Dataview.
So far I (finally) managed to get 2 comboboxes (will be more, but if it works for 2...) loaded with the same data using different dataviews (DataView1 & DataView2) so I can select a value from each combobox without the other following the selection.
But now I want to filter out the selected value from the other combobox.
This also works.
The only thing is this: If I select in combobox1 the value 3, and select in combobox2 the value 4, combobox1 will change to the value 2.
If I select in combobox1 the value 2, and select in combobox2 the value 1, combobox1 will change to the value 3.
It works also the other way arround. I can't seem to get my hands around the problem..
Does somehow the index of the items in the combobox play's part? I don't use the selectedIndex, so from my point of view it can't be..
The code I use:

I'm loading a DataGridView from a DataView which collects data from a DataTable. I use the DataView to filter, this is the

I am trying to build a filter string for my DataView, but I have run into a problem. My underlying DataTable contains values that are formatted when displayed in my DataGridView.For example, if the DataColumn contains 1.52 and the DataGridViewColumn.DefaultCellStyle.Format = "n0" then 2 is displayed.So the user sees 2, then sets the DataView.RowFilter = "DataColumn = 2", and no DataRows are returned. Is there a way to format the DataColumn in the RowFilter string? For example, DataView.RowFilter = "FORMAT(DataColumn, "n0") IN (2, 4)". This filter string should return 3 rows. If not, can LINQ do this?

I have a datagridview with transaction bindingsource I want the datagrid to show the sorted rows only not all the records when i enter a value into a textbox and click button sort.
View 1 RepliesI am filtering a dataview which is used for a datagrids datasource.At runtime when I apply the filters (using Checkboxes to determine the RowFilter text) I get an additional blank row at the top of my grid. This is then treated like a row & is filtered out with other rows that don't fit the filter criteria but comes back when I remove the filter. Basically, its part of the underlying DAtaview it seems. It's not persisited to database but I can't seem to get rid of it when I'm filtering.

2nd question. How can i bind other queries from different table to these columns. like Column[2]and Column[3] should come from a different query.
While working with an excel file (.xlsx), the data I get from it is an IEnumerable(of Dictionary). When I bind this to my datagrid, I get the problem that I only see 2 columnsI've been tracing this problem and discovered that in the first row in the excel, there are only 2 values (cell C and D). I think the binding to datagrid looks at this first row to create its headers. This results in my datagrid only showing columns C and D.

using strongly-typed ms access 2007 database , vs 10 i have a problem with datagridview filter i have 4 columns and allowDBnull is true , null value is empty my problem is that i need to have 4 textbox to filter the columns so i used in the texchanged
Me.PartsBindingSource.Filter = "Convert(partsn, 'System.String') LIKE '%" & TextBox1.Text & "%'" & " and Convert(description, 'System.String') LIKE '%" & TextBox2.Text & "%'" & " and Convert(Position, 'System.String') LIKE '%" & TextBox2.Text & "%'" & " and Convert(model, 'System.String') LIKE '%" & TextBox4.Text & "%'"
which works just fine , except for the rows which contains any null value as those rows are hidden all the time once i change the text, even when i clear the textbox they keep hidden i can only see them once the form is loaded to cut it short, i need to make a filter to the datagridview , that filter should show the rows even if one of the cells is null?
